There are three popular ways to start seeds: plastic cell trays, peat or fiber pots, and soil blocks. Each works. The right choice depends on your plants, your budget and how hands-on you want to be.
| Option | Pros | Cons | Best for |
|---|---|---|---|
| Plastic cell trays | Reusable, inexpensive, good drainage, easy to organize | Must be washed between seasons. Roots can circle in small cells if plants stay too long | Beginners and most vegetables, herbs and flowers |
| Peat or fiber pots | Plant the whole pot, so less root disturbance. Biodegradable | Dry out quickly and can wick water away from the soil. Thick walls may slow roots if not buried fully | Plants that dislike transplanting, such as cucumbers and squash |
| Soil blocks | No container waste. Roots air-prune naturally | Needs a blocking tool and a firm, well-mixed medium. Blocks are fragile | Experienced growers starting many plants |
Plastic cell trays
The default for good reason. They are cheap, last for years and hold moisture evenly. If you grow in small batches, they are hard to beat. Wash them with warm soapy water between seasons to reduce the chance of disease carrying over.
Peat and fiber pots
Because you plant the pot along with the seedling, roots are not disturbed at transplant time. To make them work well:
- Bury the whole pot under the soil surface when transplanting. An exposed rim wicks water out of the root zone.
- Tear off the bottom or sides slightly so roots can escape easily.
- Water a little more often, since the pot walls dry out.
Soil blocks
Soil blocks are made by pressing a moist, firm mix into a block with a handheld tool. There is no pot at all, so roots stop growing at the edge of the block instead of circling. They are a fun upgrade once you are comfortable with the basics, but they are not the easiest way to start.
Our recommendation
For a first season, start with reusable plastic cell trays and a dome. If you grow squash or cucumbers, try a few peat pots alongside for comparison. Consider soil blocks later, once you know how many plants you want to grow each year.
